Entropy Analyzer
Used to measure the information entropy of a file or text, which indicates how compressible the data is.
About Entropy Analyzer
Entropy Analyzer is used to measure the information entropy of a file or text, which indicates how compressible the data is. It calculates Shannon entropy by analyzing the frequency distribution of bytes in the input. High entropy (near 8 bits/byte) means the data is already compressed or encrypted and will not compress further — low entropy means good compression potential. Entropy Analyzer runs free in your browser at abovetool.com — no signup required.
